EDWIN BALL STIMPSON, OF BROOKLYN, NEW YORK.

CARTRIDGE-BELT.

Application filed June 4, 1918.

To all whom it may concern:

Be it known that I, EDWIN BALL STIMP- son, a citizen of the United States, residing in Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Improvement in Cartridge-Belts,'of which the following is a specification.

This invention relates generally to machine gun cartridge feeding belts.

In application Ser. No. 233,553, filed May 9, 1918, a cartridge .belt construction is shown and described in which comparativelylunsubstantial sheet material, such as paper, is reinforced by having longitudinally arranged cords embedded therein, strips of such reinforced material being at tached to each other to form cartridge holding loops by stitching the reinforced portions of the strips to each other at the proper intervals. This provides a very effective and simple construction but I have found that it is possible to still further simplify the structure by utilizing the longitudinally arranged cords not only for the reinforcing functiombut also as the thread members by means of which the strips are attached together to form the cartridge holding loops. Accordingly the main object of the present invention is to provide a simple and substantial cartridge belt construction of the general type referred to.

' With this and other objects in view, one feature of the invention consists in forming a cartridge belt of layers of sheet material having reinforcing cords arran ed longitudinally thereof, and in utilizing the reinforcing cords as means for Stitching the layers of material together at intervals to form cartridge holding loops.

Another feature of the invention consists in interposing spacing members between the layers of material forming the loops at the points where the layers are stitched together.

Other features of the invention will be hereinafter referred to.

In the drawings, in which a number of preferred embodiments of the invention are illustrated,

Figure 1 is a side view of a section of cartridge belt embodying the invention and showing the appearance of the belt at the end of the reinforcing and stitching operation.

Fig. 4 is a sectional view of the structure shown in Fig. 3.

Fig. 5 is a diagrammatic view showing on an enlarged scale the relation of the reinforcing cords and the strips of material making up the belt.

Fig. 6 is a sectional view of a modified form of belt in which four separate strips gflmaterial are employed in making up the Fig. 7 is a view similar to Fig. 6 showing a form of belt in which three strips of material are used, one of which is folded along the central portion to form covering layers on both sides of the belt proper.

Fig. 8 is a perspective view of a spacing member that may be usedas part of the belt structure.

Fig. 9 is a diagrammatic view similar to Fig. 5 and showing the manner in which the ipiicing member is used in making up the In Figs. 1, 2, 3, and t of the drawings there is shown a section of a partially and a fully completed belt made up of two strips of sheet material which are attached together at suitable intervals along the central portion and along one edge to form cartridge holding loops. The thread or cord members which are employed for stitching the cartridge engaging portions 1 and 3 of the strips of material together, as at the points 7 of Fig. 1, are preferably of substantial size v and strength in order that the straight line stretches 5 intervening between adjacent stitched portions 7 may be enabled to serve as reinforcing tensile members for the belt, thereby permitting the use of sheet materialsuch as paper or light and thin fabric having a low degree of tensile strength.

While two single strips of material having the width of the portions indicated at 1 and 3, or even a single strip folded over into two layers, may be used to form the belt, I referably employ two strips of the width indicated in Figs. 1 and 2 and which are folded over on themselves at 6, as shown in Fig. 4, to form the belt. The folded over portions 2 and 4 may be attached in place on the outer faces of theportions 1' andB in covering relation to the cords 5 by means of any suitable adhesive, so that the completed belt will appear as'in Figs, 3 and 4. V

It will be obvious that other arrangements of the sheet'material into'suitable layers t form a belt may be had and two modifications of this nature are shown in Figs. 6 and 7 of the drawing. In the modification shown in Fig. 6, four separate strips engaging strips 1*and'3 being preferably formed of heavier stock than that comprisingthe'outer or cord covering-layers -25 and 27. In Fig. 7 the outer covering layers 21 are preferably-formed of "a single strip of double width and doubled over at 23' into position. 5 The paper strip 21 being'comparatively thin is readily pierced by the pointed bullets 'as the cartridges'm are passed into place within the loops provided in the belt.

@It will1beseen in Fig. l that a' greater number of stitches are provided in A the stitched portions that are to form the loopsfor receiving the smaller end. 12 of the cartridges than at theother edge of the belt.

" In Fig; 5 of the drawing there is 'shown in V ent of the United States is:

17, to each other is clearly shown. spacing members are made of such material, as for example, cardboard, that the cord an enlarged diagrammatic view the relative arrangement of a; pair of oppositelydisposed cords 5 and the intervening belt strips 1 and 3. It will be seen that thc cords; 5 are arranged in a stitched formation at 71 to thereby attach the-strips l and 3'together at suitable'intei'valsto form cartridge li'old- 'ing loops. 7 j

In Fig. 8 of the drawing is shown a spacing member 17 adaptedtobe insertedbetween the'beltstrips at the-points where the strips are stitched togethe so a's'to'mint mize the extent to which the .walls of the belt must be deflected to embrace the car tridgeswhen they are put into place in the loops. The spacing membersl7 are preferably formed with enlargements) at one end that lit into the narrowed si-amateurs adjacent cartridges at the shoulders thereof. In 9 of the drawing therelation ofthe strips 13, the; cords 5 and stitches' 'l', and the enlarged ends 19 of thespacing members The members can be passed therethrough to form the stitches.
